What Is SEMRush?
Let's start right here with a quick overview of what SEMRush actually is.
If you've been doing SEO and keyword research for awhile, you've no doubt heard of the tool and maybe even tried it at some point.
If you're just learning SEO, then SEMRush is best described as an all-in-one SEO tool that helps you analyze metrics like keyword rankings, backlinks, competing websites, gaps in your content, and so much more.
The best part is, you can run this kind of analysis on your own website as well as your competitors – which is where the tool really shines.
Imagine being able to see exactly what's bringing your competition the most organic traffic and then building out content to compete with them.
That's what SEMRush does best, so let's take a look at exactly how we use it to increase traffic to our websites.
Choosing A Niche
If you're still at square one, trying to figure out what you're website is going to be about – SEMRush can help you figure it out.
While picking a niche to enter is a multi-faceted decision, one of the biggest factors to consider is the current competitive landscape.
Are there dozens of entrenched authority websites I'd have to compete against?
If so, what can I offer that will help me stand out from the crowd and carve out an audience for myself?
Another important factor is whether you niche/topic of choice actually has enough interest to make it worth your time. There are quite a few things you can look at to determine potential market size, but when you're creating a niche website one of the considerations should certainly be how often people search keywords about this topic in Google.
For example, let's say you're bound and determined to create a website to help left-handed violinists but some of the most general search terms like “left handed violin” get searched only 1,600 times per month:
That should give you pause to consider questions like:
Are left-handed violinists really a big enough audience to build an entire website for?
Would I be better off creating a website for all violinists and including a section for left-handed players? (Hint: yes)
How SEMRush Helps Choose A Niche
Of all of the different factors that go into choosing a niche, my favorite thing to look for is not-so-great website that's doing really well in terms of traffic.
My thought is, if a low authority, average quality site can do well in this niche, I can too.
SEMRush makes finding these kinds of sites very simple.
I usually start by searching some product related keywords where niche/affiliate sites are often found. In this case, I wanted to explore a niche site about owning and caring for a pet fish.
So I searched for “best aquarium filter” in the keyword analytics section of SEMRush.
After scrolling down a bit, I see these are the current top 10 results in Google:
Mentally, I cross out the ecommerce sites and sites with name recognition like Amazon and YouTube in these results.
I usually start by clicking on the domain that sounds most like a niche site to me.
For instance, if there was a result here that looked like “best-fish-filter-hq.com” – that would be my first stop!
In this case, I'm pretty sure most of the top 5 are affiliate websites – which is a great sign!
If I'm planning to create an affiliate website, I want to see that Google is ok with ranking other affiliate websites for the keywords I'll eventually target.
I start by clicking on the second result, tropicalfishcareguides.com and see this overview:
It looks like my first swing could be a homerun!
SEMRush shows that this site gets an average of 28,500 visitors from Google each month.
This number is only an estimate, and what I've found through tests by Screaming Frog and personal experience, this number is usually lower than the actual traffic.
So that 28.5K is probably more like 40K or so.
How Much Can You Make From 40,000 Visits?
Let me sidetrack for just a moment and give you an understanding of what you might make if your website was able to get 40,000 visitors for month.
As Spencer blogged about recently, we switched one of our blogs over to MediaVine and have been making about $18 per 1,000 sessions.
So assuming your site was only using MediaVine to make money, that would be around $720 per month ($18 x 40). For many affiliate sites like this one, you'll also be making money as an Amazon affiliate – which is a little harder to estimate a consistent monthly number.
However, a site like this should be making $1,000 per month easily, and perhaps several thousand per month if it's ranking well for a lot of product-focused, “buyer” keywords.
Let's Continue Evaluating The Pet Fish Niche…
The next step is to scroll down and view the full organic keyword report to see everything they are ranking for to get all of this traffic:
Now I can see all 15,000+ keywords, which are sorted by the (estimated) amount of traffic they bring the site:
You can really go down the rabbit hole at this point by slicing and dicing this data to find all kinds of potential keyword targets, but we'll get into that a bit later.
For now, my next question is how authoritative is this website?
My favorite way to get a quick number on this is to jump over to Moz's Open Site Explorer and check the domain authority. (Moz is a paid SEO tool as well, but they give you a few free searches per day).
It shows a domain authority of 14, which by any standard is a low authority website. Once a site reaches a DA of 30+ that's considered at least decent authority – so I really try to focus on sites in the low to mid 20's.
Finding something is the teens that's getting a bunch of organic traffic is like hitting the jackpot.
All of this talk about authority simple means that as a newer site, I should be able to compete for many of the keywords they rank for without having to build tons of high authority backlinks.
Ideally, from here I'd repeat this same process and find at least one more site (the more the better) with similar numbers.
This would give me confidence that I could start a new site to compete with them and expect to see traffic in a reasonable amount of time.
Of all the features that SEMRush brings to the table, the one I've found most valuable is how easy it is to “steal” keywords from competing sites.
What does this mean exactly?
As I showed earlier, you can pull up any site and SEMRush will show you all the keywords in their database the site ranks in the top 100 for.
Best of all, you can filter and sort to your heart's content – so you can really find some gold nuggets using this tool.
Let's continue with our pet fish example.
Mastering Keyword Theft
Of course when we talk about “theft” and “stealing” we aren't really talking about something that is illegal or unethical. This information is readily available, but tools like SEMRush and Ahrefs just make it much easier to find.
You're really just seeing what's working for your competitor, then trying to make it work for you.
In the fast food world, that's like Subway doing the $5 Footlong promotion and then when it's a hit, every other fast food restaurant starts offering some special meal for the $5 price point.
So you shouldn't feel like you're playing dirty by doing the things I'm about to show you.
Find The Buyer Keywords
We often refer to obvious affiliate keywords as “buyer keywords” because they are things people search when they are about to buy something.
- Best Kitchen Scissors
- Yeti Cooler Alternative
- Top Kids Goggles 2018
- Samsung Microwave Reviews
If you can get organic search traffic for buyer keywords like this, you then have an opportunity to compare and review products the searcher might be interested in and then send them to Amazon, Walmart.com, etc. to buy it and then you, being an affiliate, make a commission on the sale.
Buyer keywords are usually some of the most profitable keywords on your site.
In SEMRush, you can start by going back to the “Organic Research” page for TropicalFishCareGuides.com and using the search box near the top of the list to type in the word “Best.”
Here's what happens:
Notice the list is filtered and now it only shows you the keywords that contain the word “best.”
With a low authority site like this, I don't go much further in my analysis. I work from the assumption that if they can rank page 1 for a keyword, so can I.
So I'd open up a Google Spreadsheet and start copy/pasting in keyword ideas that seem like a good fit – excluding closely related terms.
For example, if I saw “best betta fish tank” and then “best tank for betta fish” that's really the same thing – so I'd only put one in my spreadsheet.
You'd likely have dozens of keyword ideas just from this first search, so now it's time to try some other common buyer keyword modifiers.
Here's what happens when I change my filter from “best” to “review:”
Now if I want to get into reviewing specific aquarium filters and other accessories, I've got a bunch of ideas that I should be able to rank for.
You can repeat this process with as many words as you'd like, on as many sites as you'd like.
Imagine how many keywords you could come up with in an hour just by using this one technique.
Filters Gone Wild
Filtering my list of keywords to just show those that contain “best” is a very simple application of the filtering concept.
However, you can filter on a ton of useful data points in SEMRush to find more keyword ideas.
When you click the “add one more” button, you can build out a more specific filter:
Here's some other simple but powerful filters I use to find excellent keywords with SEMRush:
Find The Best of The Best
One filter I like to run is to take my buyer keyword modifiers like “best” and combine it with their search position. By doing this, I can say only show me the organic keywords where they rank in the top 5 of Google.
Here's what that looks like:
If I'm looking for the easy wins, I know if a DA 14 site is in the top 5 of Google then the keyword difficulty isn't too bad.
Find High Volume Winners
I've stated many times that I'm a fan of going after low search volume terms. Even if something gets searched 10 times per month, I'll still target that keyword if it seems like a good fit for my site.
However, we all know that ranking for the higher volume keywords that get searched thousands of times per month are important – as you can be rewarded with a greater amount of traffic.
Here's a filter that shows me every keyword that gets searched at least 1,000 times per month and our tropical fish site still ranks on page 1 of Google: (Notice only 50 of the 16,000 keywords they rank for meet this criteria)
Find Long Tail Gems
We love long tail keywords for many reasons!
One of those reasons is because they are usually easier to rank for when you build content that addresses that specific question.
Here's a filter that will show me all the keywords they rank for with search volume over 1,000 and the keyword has more than 5 words in it:
Only 12 of the 16,000 keywords meet this criteria, but these would be some excellent keywords to build informational content around:
Of course, 1,000 searches per month is an arbitrary number. If I really want to get more ideas for informational content, I could change that 1,000 to 100 and get many more results:
Discover New Competitors
You know that your site has competitors – but do you know who those competitors are?
My guess is that you probably know a few sites you compete with, but there are probably many more out there that you've never heard of.
What if you could find those competitors and do some of the same reverse keyword search (AKA keyword stealing) we just talked about?
Finding previously unknown competitors is another place where SEMRush really shines.
Once I was done picking through the tropical fish site we've been using as an example, I can click on “competitors” to see a list of sites very similar to it:
SEMRush sorts the competitors in a very helpful way by default, which is the competition level. In other words, they find the sites that have the most keywords in common and put them at the top.
So you'll usually find some really closely related sites right away, and can click on them to do the analysis and keyword theft we demonstrated.
Create A Competitor List
The next thing you want to do is start copying the relevant competitor domains into a separate page of your spreadsheet.
This way you don't forget or lose any of them and if you get distracted, you can come back at a later date and mine their site for more keyword ideas.
You're going to get the most ideas from sites that rank for a lot of keywords – like the first one in the list – Aquarium Adviser. They rank for 18,300 keywords and based on the name, I'm willing to bet that many of them are buyer-focused keywords about different types of aquariums.
I'll avoid adding e-commerce sites like Amazon to my list, because I'm not really an e-commerce store. The same goes for sites like Wikipedia or non-profits – they aren't really competitors in my mind, so I try to only focus on other niche/affiliate sites.
The reason for this is because it's important to know that Google is willing to rank a niche site for a given keyword. If the top 10 results of a keyword are all e-commerce sites that sell a product, I'll usually stay away from that keyword because I know that Google is looking for e-commerce results only.
By only evaluating other niche/affiliate sites, I can still work from my rule of thumb which is: if they can rank for it, so can I.
The next step to build out a more complete competitor list is to click on one of the competing sites, then repeat the process.
So I'd start by clicking on acquariumadviser.com and checking their competitor list:
Notice our friends over at TropicalFishCareGuides are on top of the list, but then it gets really interesting.
Sites like FishTankAdvisor.com that ranks for over 24,000 keywords is next on the list, but it was nowhere near the top of my competitor list of TropicalFishCareGuides.
In fact, there are several sites in this list that I might have missed if I would have only evaluated the competitors of the first site.
You can repeat this process as many times as you need to until you have a solid list of dozens of competing sites to pull keyword ideas from.
I'm calling a timeout right here to address the oft cited 80/20 rule. That 20% of what you do produces 80% of the results.
That's where you're at right now with SEMRush.
I'm going to go into a few other useful features, but the combination of finding all the weak competitors in a niche and filtering to “steal” their best keywords is the process I use over and over again to create a content plan for my websites.
If I was building out a pet fish site, I'm confident I could have a list of 100+ REALLY good keyword ideas by spending a few hours doing the process I just outlined.
If you're serious about building a successful niche site, the things we just covered make SEMRush worth buying.

Time In: Gap Analysis
Zach Morris has ended the timeout session and we're back to live action.
The next aspect of competitor research with SEMRush is more helpful once you've got an established website.
So for this example, let's assume that I am the owner of tropicalfishcareguides.com and I want to quickly find topics and keywords that my close competitors rank for, and I do not.
Want to See My Advanced Keyword Research Strategies that Even a Beginner Can Learn?
Read my comprehensive guide on stealing keywords for competitors. I use this tool to cherry pick the keywords that I know I can rank for quickly...even if my site is newer.Read the Strategies Here
I could click on the Gap Analysis, Keyword Gap and then enter a competing domain, followed by my domain, and then a second competitor after that:
Then, I can click on the intersecting circles between each domain and make sure the first one is set to “unique to the first domain's keywords:”
Between the second and third domain you select “common keywords” and then click “go” to search:
Then, you'll get a list of keywords that both of those sites rank in the top 100 for, but you're nowhere to be found. The goal here is to find more keyword ideas, of course, but also looking for higher level categories that you may be missing.
Looking at the results below, maybe I should be doing some content about aquarium gravel, protein skimmers, and CO2 regulators:
Like everything else in SEMRush, I can add advanced filters to this list and run more gap analysis reports using other competitors I've listed in my spreadsheet.
Another great way to use gap analysis for an established blog is finding out when your competitors are on page 1 of Google and you're on page 2+.
This could be an opportunity for you to improve your SEO or do a content refresh and improve some old blog posts to boost them in the search engines.
The SEMRush blog has a fantastic write-up on how to do this.
Zero In On Top Pages
The final slice of the competitor analysis pie I'd like to share with you is taking a long look at which pages on your competitor's websites get the most traffic and rank for the most keywords.
When you're looking at an organic keyword report, many of the keywords you see are coming from a single page on the site.
For example, there might be hundreds of keyword variations about betta fish food that my competitor ranks for, but all those rankings are for a single page of aquariumadviser.com/betta-food.
So from an SEO perspective, does it make more sense to have one all-encompassing post about betta fish food that targets dozens of keywords?
Or is it better to have dozens of posts about betta food, each one targeted towards a different keyword?
The answer is that “it depends”, but usually going with a longer post that goes deep on a topic is more beneficial in terms of SEO.
The best way to see how your competitor handles this question is looking at the pages report in SEMRush:
This report estimates that the page getting the most organic traffic is the post about feeding a betta fish. I can see that it ranks for just over 600 different keywords:
If I click on that number, I can take a look at all 602 keywords this page is ranking for. By default, that list will be sorted by the terms that bring in the most traffic:
As you can see, these are mostly variations of the same thing:
- How often to feed betta
- How often do you feed a betta
- How often do betta fish eat
That's really not very helpful for our purposes.
The way I like to use this report is to sort by keyword volume and find out what they are ranking for that gets searched most often:
Notice that the page isn't ranked on page 1 for many of these keywords, but that's ok.
What you're looking for here are interesting keywords that they likely could be ranking well for with this post, had they optimized for it.
As I scan this list, I can already see my outline coming together for my big post about betta fish food:
Betta Fish Food would be my primary keyword, then I'd have subsections on topics like:
– What do betta fish eat?
– How often do you feed betta fish?
– What do I do if my betta fish won't eat?
And probably a number of other related topics and questions that fit with my primary keyword.
What Else Does SEMRush Do?
SEMRush is just about the total package in terms of an SEO tool. So while I've gone in-depth on how we use it to spy on our competitors and build out a keyword and content plan – there are plenty of other features that I've not talked about.
I'd like to at least highlight the notable ones for you briefly:
While Ahrefs is considered by many to be the gold standard in backlink analysis, SEMRush has a helpful backlink analytics module to check both your and your competitors backlinks:
We all know that backlinks matter for SEO, so using SEMRush to see where you competitors best backlinks are coming from may give you some places you can reach out to and get a link from the same page.
Here's a look at a few top links for our example site. Notice that we can filter to only show “follow” links if we'd like, meaning those that pass that tasty SEO juice. You can also see the anchor text being used to link to your site:
Historical Ranking Trends
This is found on the same organic research page we used earlier for finding our competitor's top keywords. It's a helpful graph that shows how your rankings and organic traffic have fluctuated over time:
Ideally, a healthy site will show a steady growth over a period of years. If you're evaluating a site to purchase, look here for some drastic dips in traffic or rankings as a potential red flag of a Google penalty.
Keyword Difficulty Score
I am partial to the KC score in Long Tail Pro when it comes to getting a reliable number to know just how tough it's going to be to rank for a keyword.
SEMRush does have a built in keyword difficulty score that you can see on any organic keyword report. The idea is the same, the higher the number, the harder it is to rank for.
With the way I use tool, I start by finding domains that lack authority and checking out their best keywords. So for my purposes, I don't even check the SEMRush keyword difficulty score.
As stated earlier, if I'm looking at a low authority site – I work from the assumption that if they rank for a keyword, I can rank for it too.
PPC Advertising Research
Admittedly this isn't a module I make use of, as I don't run any paid search ads for my sites. However, if you do – SEMRush has a boatload of helpful information in the Advertising Research module.
For example, I can click on “Ad Copies” and see what an e-commerce player like Petco is running ads for:
It just so happens that “aquariums” happened to be one of their top campaigns based on the number of keywords they run ads for.
In the screenshot above I've clicked on the 810 keywords and now I can see an expanded list of exactly what they are.
My guess is that Petco probably has some good data on what people are searching for when they are about to buy an aquarium…
You can setup a variety of different reports, alerts, and functions inside of a “project” on SEMRush.
This truly can become a one stop shop for the health of your site. Here are some things you can setup in a project:
Social Media Monitoring & Scheduling
Yes, SEMRush does social media as well. Connect your major accounts and schedule out posts from a single location:
You can also track engagement on your social channels as well as brand mentions that may be happening so you can respond or at least be aware when folks are discussing your site on social.
Making the move from http to https? A site audit can check the health of your site to make sure visitors aren't getting mixed content errors.
You can get helpful insights on possible performance issues or crawlability in the eyes of a search engine, as well as reports on broken links you need to clean up.
A newer (still in beta at the time of this writing) feature inside or projects is backlink prospecting. You can enter 10 keywords that are important to your site, plus list out your closest competitors and SEMRush will work a little magic and show you what your best link targets might be.
You can also communicate with site owners and track progress inside of the tool if you really want to have everything under one roof.
The backlink audit feature lets you find and disavow crappy backlinks that you don't want pointing to your site, which could help you avoid a search engine penalty by being proactive and letting Google know you didn't build those links.
SEO Content Audit
One of the hot tools in SEO these days is Market Muse which lets you analyze the top 10 results for a given keyword and figure out how long your content needs to be and what keywords you should be using if you want to rank well for that keyword.
Well, the SEMRush SEO Content Audit gives you a poor man's version of that. Here's the result when I analyzed “best betta fish tank:”
This gives you a recommended article length based on the top 10 results (2,213 words) and suggests LSI keywords (semantically related) which should give you some subtopics to make sure you include – like talking about filtration systems and fluval edges (whatever those are).
Did I Miss Anything?
Our SEMRush Review train is headed back into the station.
So now it's time to ask you – what did I miss? We're talking about a tool that has so much you can do that it's almost overwhelming, so I'm sure I've neglected to talk about some feature.
With that said, my humble opinion is that the competition spying and keyword stealing features make this tool worth it if your primary objective is to create a solid content plan for your website.
The rest of this stuff is just gravy.
There just happens to be a lot of gravy in this case.Click Here To Try SEMRUSH
